How to check JDK version in Oracle?

Question

We have a Java class within our Oracle DB and recently one line of code in that java class is throwing an error:

static BASE64Encoder B64 = new BASE64Encoder();

We are seeing error

java.lang.ExceptionInInitializerError

on this line of code.

I am not sure what has changed on the DB side as we don't have SYS privileges or access to host.

I wish to check the JDK version running our Oracle DB --

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production.

Thank you.
